Aironet 1310 APs dropping connections

Hello, I have two Aironet 1310s outdoors - one on a boat and the other on a building. I have one ANT24120 antennas attached to each AP. I am trying to determine why I am having dropped connections. Any help would be appreciated.

1) I do not know if anything has changed (at least not with each AP or antenna). I am guessing there is more RF noise. I ran a product called wi-spy and channelizer. There was a lot of competition, so I hard-coded a channel that was consistently lower in noise.
2. I have reset both bridges.
3. I will not have physical access to both bridges till Monday.
4. I am trying to get up to about 5 miles. I am having intermmitent issues while docked as well.

Aironet 1310 bridge does not reestablish connection

We have an aironet 1310 bridge installed (root/non root) where the non root drops sometimes the signal when the morning sun is in direct line with the link. This blackout problem is known. What bothers me is the fact that the bridge does not automatically reestablish the association...
Once it has been lost we have to restart the Air 1310, then it re-associates. Is there a workaround or an automatism?
Thank you for your suggestions.
Bert

This should be automatic. I had a client have this problem once, and we found that the problem was actually with the 1310 being configured in diversity mode. The 1310 would disconnect in tough weather conditions and try to connect to the little metal stub that comes on the bridge. The signal was too weak to establish a good connection, but for some reason it would not switch back.
So check to see if you have diversity mode enable, and disable it if it is. If that's not the problem, I'm not sure what it could be. Have you tried upgrading the IOS?

Aironet 1310 Bridges keep losing connection

There was a similar thread about this last year and I tried what was listed in there to no avail. I have 2 Aironet 1310 bridges, one as a route bridge and the second as a non-route with clients. These worked great for nearly a year, we had no problems keeping the connection up. They were not connected for the last few months but nothing was changed on the configuration, when I put them back up they reconnected just fine and worked for about an hour, not they randomly disconnect with the same message in the log entries below. Is there something wrong with them now? The are using the same antennas as before and are in the same exact locations.

I am not at the remote location any more, but the route bridge had a signal of -78 dB and a SNR of -22 dB. The non-route has -77dB for signal and a SNR of -22 dB. The location has line of sight, over water with nothing in the way.
Since I last posted I changed the fragmentation and RTS thresholds back to default from 4000 and it has been up for 24 hours now. I am hoping that it has made the difference.

I need Bandwidth, Filtering & Accounting work with Aironet 1310

Hi Mates,
Please I need an affordable Cisco hardware or software (for SMB) to control about 200 clients in my wlan (hotsopt internet caffe)
all work with two Aironet 1310 .
I'm not concerned about security in the first palce, but Bandwidth, Filtering & Accounting.
MY Regards
Saher

Just to be clear: You want to give wireless access to 200 clients over two APs *?at the same time?*
That would be a Very Bad Thing, and almost certainly not possible.
Generally speaking, with "normal" traffic (no such animal exists), you can expect to run 20 - 30 clients tops per AP.
It is not likely that you can impose your restrictions at the AP level. More likely, you'd want to do it at the switch, possibly at the router.
The problem is that the AP acts as a hub: shared bandwidth, and collision avoidence. Basically it boils down to every client getting a timeslot to communicate. When you have too many clients on a single AP, the clients are not talked to often enough, and you get association drops. Before association drops, you get really poor performance that progresses to request timeouts.
The other issue is the uncontrolled mix of clients that you're likely to see. If one client is using 802.11b (11 meg), the net effect is an additional drop in available bandwidth.
The bottom line is that it's not a plan that's likely to succeed.
You may want to investigate 802.11a (5GHz). It has more non-overlapping channels (802.11g has three). To get that many poeple in a confined space and maintain acceptable connections and performance, the extra bandwidth will help a lot.
Good Luck

Cisco aironet 1310 Outdoor access point

I am looking at outdoor access points, I want to stick with Cisco aironet, we currently have 6 of them that are 6 years old and running great, one has had a problem because of humidity, dried it out and relocated and we are good again.
I was looking at the Aironet 1310 Outdoor access point, but I can't find much information on it. I am looking to see how many SSIDs can be setup, we currently have 2 one private, and one public, this is done with VLANS. I am also looking at finding out about the power injector, it converts to coaxial cable, it has 2 RJ-45 and 2 Coaxial, does this mean if we get 2 access points, then I only need 1 power injector?
Thanks for any help you can give.

Rusty:
AP supports up to 16 SSIDs to be configured.
Multiple SSIDs with VLANs configuration is done almost the same way you do with current Aironet APs.
see here: http://tiny.cc/0qwnkw
You also need one power injector per AP. Each AP should use it's own power injector.
The two coaxial output in the power injector both are used to be connected to the AP (see below image).
The RJ-45 connectors in the power injector one of them is for Console connectivity and the other for network ethernet connectivity.

Aironet 1310

hi everybody i am santosh , i have a cisco aironet 1310 running 12.4(10b)JA1 and c1310-k9w7-mx.124-10b.JA1/c1310-k9w7-mx.124-10b.JA , it was working fine but suddenly i found that it has gone to AP mode while all these days it was working in Bridgemode . could any one tell me how to revert it back to bridge mode .

You are correct. The power injector is just that and the bridge unit actually has all the intelligence in it. The power injector is just your interface connection to the unit for console and ethernet and provides power to the bridge.

Upgrading IOS on Aironet 1310

I want to upgrade the IOS on a couple of our Aironet 1310s but do it wirelessly. The bridges I am upgrading are not accessible at the time I wish to carry out the work which is why I am not doing it via a wired connection. It isnt an ideal situation but an alternative requires an outage during working hours.
A recently purchased 1310 had a sticker on it saying the radio interface is disabled by default in newer IOS images. Does this mean that when I upgrade the software it will automatically disable the radio interface when I reload? If that is the case I will have no alternative but to organise an outage.

hope this URL will be of help.

Aironet 1310 config

I have a remote location at one of my plants that needs voice for safety purposes, but would cost far too much to trench and install fiber. I plan to use 4 Aironet 1310 wireless bridges to connect to a 3560 8 port switch from two different directions. We need redundancy since the signal from one 1310 link could be blocked. Is it possible to configure the bridges to failover in case of loss of signal from one pair? For that matter, how do I configure these two connections to the network to avoid conflict with voice packets?

Hi,
There is no way to do this by configuring something on the bridges, as there are no
features on the bridges that we can configure on them to say: "Monitor
another wired link between these two sites, and if that one goes down, then
associate with the other bridge to start passing traffic over here, or use
both links load-balancing traffic between each other.

Aironet 1310, power injector and poe cable

Hello,
Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?
The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.
But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...
Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)
Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.
Thanks in advance,
lachapelle

Hi lachapelle,
Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.
Dual coaxial cable to run from the power injector to the 1300. See attached notes:
Cisco Aironet 1300 Series
Cisco Aironet 1300 Series Access Point/Bridge Power Injector
The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate up to a 100 meter coaxial cable run plus 100 meters of indoor cat5 cable?enabling total cable runs up to 200 meters. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.

Ethernet Ports
The access point/bridge dual-coax Ethernet ports consists of a pair of 75-ohm F-type connectors, linking the unit to your 100BASE-T Ethernet LAN through the power injector. The dual-coax cables are used to send and receive Ethernet data and to supply inline 48-VDC power from the power injector to the access point/bridge.
Power
The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.

Aironet 1310 Antenna question

Hello,
ive got a question about the antenna of the aironet 1310. is there any difference between AIR-BR1310G-E-K9 and AIR-BR1310G-E-K9-R in basic configuration?
we had a bridge between 2 AIR-BR1310G-E-K9. but the non-root bridge went broken due its age. (connector pin was broken and couldnt get it out)
we had an AIR-BR1310G-E-K9-R on spare, so we only replaced the antenna but we coulnd not get a connection between the 2. diddnt change to power injector or config.
after som fiddling with the broken antenna we managed to get the pin out. changed the wire between the antenna and power injector and placed it back. and it worked like a charm.
so does anyone has an awnser for me? add 2 pictures. the only difference i can see are the 2 extra ports on the K9-R.
AIR-BR1310G-E-K9
http://i50.tinypic.com/uy4bn.jpg
AIR-BR1310G-E-K9-R
http://i49.tinypic.com/fwlfzo.jpg

The 'R' at the end is supposed to specify that it's the model with RP-TNC connectors for an external antenna. The model without the R should have an internal antenna.

Lost The Cisco Aironet 1310 Web Interface????

I've been having connection issues with my (2) Aironet 1310, which are setup in a bridge p2p mode. A few weeks ago we had a power outage due to a lighting storm. Well, it knocked out my non-root bridge (not connecting to the root). So I brought it back to check the configurations, but when I try to use the web console all I get is the following page:
When I click the "Web Console" link it takes me to the following page:
Is there a way to get the original web console page back?

here is the command..
archive download-sw / force-reload /overwrite tftp:///
Example..
archive download-sw / force-reload /overwrite tftp:///c1310-k9w7-tar.124-21a.JA1.TAR
to get the .TAR, go to the folder where the image is saved and then Tools >> folder options >> view >> check >> show hidden files and folders.
Now click on the image and then copy the image name and then paste the same on the CLI... then this come as IMAGE.TAR that is.. c1310-k9w7-tar.124-21a.JA1.TAR instead of c1310-k9w7-tar.124-21a.JA1
it should be c1310-k9w7-tar.124-21a.JA1.TAR
lemme know how this works out for you!! if you face any difficulties while upgrading please open up a TAC case.. we wil solve this in less than 5 minutes... and the network wil be back up!!

Multicast for Aironet 1310 WGB and 1242 AP

I have configured a Aironet 1310 bridge as a WGB and is connected to a Aironet 1242AG AP wirelessly!
A sensor(IP device) is wired into the 1310WGB. The sensor needs MULTICAST to operate!
I checked the DETAILED STATUS of the RADIO and both the 1310 and 1242 are blocking multicast!
The RELIABLE MULTICAST TO WGB option is enabled on the 1242AP already! No luck as yet!
Any thoughts??

Have you seen this thread??

Configuring Aironet 1310 as a wireless bridge!

I want to connect a specific SENSOR(IP DEVICE) to my network wirelessly!
{ The application is as simple as connecting a Trednet wireless adapter to the TV to access the HOME WIRELESS NETWORK to WATCH NETFLIX on INTERNET TV!
But my Client wants to use AIRONET 1310 bridge ONLY! This is where the problem starts! }
Currently the sensor connects to my office network via CAT 5 Cable, I intend to remove the long cable and use the 1310 bridge next to the sensor connected with a SMALL patch cable to provide the direct network connectivity and bypass the LONG cables to the switch!
I'm tired of trying to configure this bridge to connect to my office network. I just can't find the settings where I can configure the SSID and Security key of my office wireless network on the GUI for it to connect wirelessly.
Extra information:
Office Wireless AP : Linksys wrt54G
All the sensors are originally connected to a dedicated switch which is patched to the main network.
My computer connects wirelessly to the network and I can access the sensors on the same network(the PC and sensors need to be on the same subnet)
My office network has 7 such sensors and I'm experimenting with 1 sensor to go wireless( I know I would need 1bridge per sensor and it would be expensive, but thatz what the client wants!!!)
Thanks,
Viren Mathuria

I have setup the Aironet 1310 as a WGB. But the example shows open authentication for AP.
My AP which is a Linksys WRT54G has a WPA PERSONAL TKIP authentication.
Need some inputs on configuring the Authentication on WGB.
I looked at different options in :
Client Authenticated Key Management
AP Authentication
But nothing seems to work, specially when I tried the DEFINE CREDENTIALS in AP Authentication, it asks for a USERNAME(I just have the Authentication KEY)

AIRONET 1310 BRIDGE CONFIGURATION

Hi I desperately need help. I am trying to configure 2 Aironet 1310s as Root bridge and non-Root bridge. When I configure the root bridge the wireless interface remains up.When I try to configure the non-root bridge the AP/Bridge will assume the role of non-root bridge and immediately disable the wireless interface with line potocol down .I tried swapping the roles and still get the same proble. I am running IOS version 12.4(10b)JA

Hi
I finally made a breakthrough. The issue here is the internal antannae. It seems it does not work well. I tried to use the antannae from the linksys wireless router and enabled them, I one time got the radios associate. I connected to the network and was able to ping the Pcs on each end of the network.
Now what I am interested in finding out is why those radios cannot work with the internal antannae. The model I have is AIR-BR-1310-E-K9-R.Is this designed to come with an internal antanna. I was able to pick one bar from my laptop from within 5 metres from the bridge. so what is the issue with these radios.

Configuration of a Point to MultiPoint link with Cisco Aironet 1310 bridges

Hi All,
The previous problem of which I started another conversation here:
http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=General&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddba023
somehow dissapeared. It could have been a problem of interferences.
I have another issue with other (multipoint) wireless WAN link, which I hope has a solution.
On the central node, we have an Cisco Aironet 1310 bridge configured as root-bridge. It has a panel of four vertical polarity 17 dBi panel 90? antennas, with more than enough gain (there is a 250 mWatts 802.11 b/g amplifier, before the 4-way splitter) and excellent line of sight to three remote bridges.
The three (03) remote bridges are also Aironet 1310 models, confidured as non-root-bridges.
The problem we have is that it seems that when the three remote links operate concurrently the amount of lost packets is huge. When I shutdown the radio interfaces of two bridges, the remaining bridge makes an excellent link with the central node.
It seems that some hours are more critical than others, also the links operate much worse when there is some (small) network traffic in them.
I have read the 1310 manuals, and I can't find a sample configuration for point to multi-point links.
Does someone knows what radio interface configuration should I need to use to establish better quality communication?
I mean, perhaps the 1 x root - 3 x no root configuration is not recommendable for the multipoint link configuration.
Any hints will be welcome.
Best Regards,
Igor Sotelo.

Hi All,
Thank you for the information. I configured the distance on the root bridges, but the links showed instability.
I'm using a bi-directional amplifier. It has two pieces. According to the manuals, one is installed indoors, the other outdoors. I'm not sure if the indoors piece has the transmition module or it's only the injector.
We could establish connection at 7 km (around 4 milles) distance from the central point, using 24 dBi antennas on the other side.
However, we have issues with a near located point that is only 1.2 Km (around 0.8 milles) away and has a 13 dBi integrated patch antenna. The signal strenght value we get there is in the -62 to -68 dBm range, and is noticiably (5-10 dBm) lower than the strenght we get at other points of the link. And I have trouble establishing a high quality link with that point, using OFDM modulation. I tend to think that if I remove the amplifier I'm not going to reach that point at all. The EIRP on the central iste is 34 dBm / 2.5 watts, without amplifier it would be 26 dBm / 0.4 watts.
On the opposite sites the EIRP is 33 dBm / 2 watts using CCK or 28 dBm / 0.63 watts using OFDM.
When one looks at the central site from that point, an Motorola Canopy with passive reflector (EIRP 48 dBm or around 64 watts) can be seen. It doesn't have the same direction, but the opposite site must be large distance and could interfere with my wireless network. Attached is an amplified photo of the view. It's safe to assume that the Canopy operates in the 2.4 GHz frequency range.
Once I connect the point at 1.2 Km, the multipoint link loses its quality, and soon the lost packets get too frequent.
The CCK seems to be much more interfered than OFDM, I guess because of that canopies.
Another thing I'm wondering about is if the Aironet 1310 can continuosly switch CCK-OFDM over the same point - multipoint link, without losing packets.
What other parameters should I tweak? Is there a way to avoid interferences fromt the canopy?
I would like to apply 100 mWatts local power using the radio with OFDM, but it seems that's not possible.
Best Regards,
Igor Sotelo.
